浅谈高中化学概念的导入策略

摘要

在化学概念教学实践中，要关注学生已有的知识基础，并采用多种方法。通过三种导入新概念的策略院提供适当的范例，促进新概念的形成；找准恰当的已知概念，促进新概念的链接；消除混淆，促进相互有关联概念的联系与辨别。使学生在不经意间进入新概念的学习中，对概念的理解更容易。%In the practice of chemistry definition teaching, it is important to pay attention to students' existing knowledge base and use a variety of methods. This paper introduces three strate-gies of introducing new definitions:providing appropriate exam-ples to promote the formation of new definitions; identifying ap-propriate known definitions to promote their connection with new ones;eliminating the confusion to promote the interrelations and distinguishing among relevant definitions. It aims at enabling students to inadvertently enter new definition learning and un-derstand definitions more easily.
